[jira] [Reopened] (OAK-7326) Add a way to disable the SegmentCache

     [ https://issues.apache.org/jira/browse/OAK-7326?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Dürig reopened OAK-7326:
--------------------------------

Reopening as I think there is a problem with eviction of segments in the empty cache: segments put into the empty cache should get evicted immediately AFAIU.

> We should implement a way to disable the segment cache. This enables us to establish performance baselines and better understand locality of reference without the distortion of the cache (e.g. see OAK-5655).
